Soften the cream cheese to room temperature, either by removing from the fridge an hour beforehand, or carefully soften it the microwave in 5 to 10-second increments.
Add the cream cheese and buffalo sauce to a mixing bowl. Whisk together until mostly smooth--a few lumps are okay.
16 ounce chicken
Add the shredded chicken to the bowl of buffalo sauce & cream cheese and stir to combine.
Preheat the oven to 375°F. Slice your mini peppers in half length-wise. Do not de-stem. Arrange the pepper halves cut-side up on a parchment-lined sheet pan. Use a spoon to remove seeds if needed.
16 ounce mini peppers
Scoop a spoonful of the buffalo chicken mixture into each pepper half until they are all filled. Place them back on the sheet pan.
Sprinkle a little bit of shredded cheddar on top of each pepper.
1/2 cup shredded cheddar
Bake at 375° for 10-12 minutes until the cheddar is melted. Remove from the oven and serve warm.
